A new simple method for the treatment of waste water containing Cu (II),Zn(II) Ions using adsorption on driedConocarpus erectus leaves

Abstract

A new simple method for the treatment of waste water effluent containing Cu(II), Zn(II) was developed using driedConocarpus erectusleavesas a low-cost natural . Batch experiments were conducted to determine the effects of varying adsorbent weight, pH, contact time, metal ion concentration and temperature of adsorption. The adsorption of cu (II) was found to be maximum (94.7%) at pH9, at 25°C, metal ion concentration 100 ppm , contact time 60 min andSpeed Shake(185rpm) . adsorption capacity of Cu (II) and Zn were found maximum (94.7% and 93.3%) respectively at optimum conditions. The order of the removal of the efficiency of these metals was found Cu> Zn. Freundlich isotherm was found to be suitable for the adsorption of Cu(II),Zn(II) ,functional groups[(C-N ,((C-O),(C=O),(O-H)] identification was given using FTIR spectrophotoscopy.
